Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for transmitting data information and control information by a transmitter in a communication system, the method comprising: identifying an amount of resources to be used for control channel transmission within a predetermined maximum amount of resources available for control channel transmission among total resources of a subframe; mapping control information onto the identified amount of resources to be used for the control channel transmission; mapping data information and a reference signal onto all remaining resources of the subframe, other than the identified resources used for the control channel transmission among the total resources; and transmitting information related to the amount of resources to be used for the control channel transmission, through a predetermined control channel; and transmitting the mapped control information, the mapped reference signal, and the mapped data information.
2. The method of claim 1 , wherein the amount of resources to be used for the control channel transmission varies in a next subframe.
3. The method of claim 1 , wherein the resources are OFDM symbols.
4. The method of claim 3 , wherein the predetermined maximum amount of resources available for the control channel transmission among the total resources is 3 OFDM symbols.
5. A method for receiving data information, a reference signal, and control information by a receiver in a communication system, the method comprising: receiving information related to an amount of resources to be used for control channel transmission within a predetermined maximum amount of resources available for control channel transmission among total resources of a subframe; receiving the control information mapped onto the identified amount of resources to be used for the control channel transmission, and the reference signal and the data information, which are mapped onto all remaining resources of the subframe, other than the identified resources used for the control channel transmission among the total resources; and demapping the control information, the reference signal, and the data information, based on the information related to the amount of resources to be used for the control channel transmission.
6. The method of claim 5 , wherein the amount of resources to be used for the control channel transmission varies from a previous subframe.
7. The method of claim 5 , wherein the resources are OFDM symbols.
8. The method of claim 7 , wherein the predetermined maximum amount of resources available for the control channel transmission among the total resources is 3 OFDM symbols.
9. An apparatus for transmitting data information and control information in a communication system, the apparatus comprising: a controller for identifying an amount of resources to be used for control channel transmission within a predetermined maximum amount of resources available for control channel transmission among total resources of a subframe, mapping control information onto the identified amount of resources to be used for the control channel transmission, and mapping data information and a reference signal onto all remaining resources of the subframe, other than the identified resources used for the control channel transmission among the total resources; and a transmitter for transmitting information related to the amount of resources to be used for the control channel transmission, through a predetermined control channel, and transmitting the mapped control information, the mapped reference signal, and the mapped data information.
10. The apparatus of claim 9 , wherein the amount of resources to be used for the control channel transmission varies in a next subframe.
11. The apparatus of claim 10 , wherein the resources are OFDM symbols.
12. The apparatus of claim 11 , wherein the predetermined maximum amount of resources available for the control channel transmission among the total resources is 3 OFDM symbols.
13. An apparatus for receiving data information, a reference signal, and control information in a communication system, the apparatus comprising: a receiver for receiving information related to an amount of resources to be used for control channel transmission within a predetermined maximum amount of resources available for control channel transmission among total resources of a subframe, and receiving the control information mapped onto an identified amount of resources to be used for the control channel transmission, and the reference signal and the data information, which are mapped onto all remaining resources of the subframe, other than the identified resources used for the control channel transmission among the total resources; and a controller for demapping the control information, the reference signal, and the data information, based on the information related to the amount of resources to be used for the control channel transmission.
14. The apparatus of claim 13 , wherein the amount of resources to be used for the control channel transmission varies from a previous subframe.
15. The apparatus of claim 13 , wherein the resources are OFDM symbols.
16. The apparatus of claim 14 , wherein the predetermined maximum amount of resources available for the control channel transmission among the total resources is 3 OFDM symbols.
